CARIBURETOR Application filed June 1, 1931. Serial No. 541,162.

This invention relates to improvements in carburetors, and it is the principal object of my invention to provide a carburetor equipped with means for controlling and regulating the flow and admixture of air and fuel in the desired proportions by atomizing the explosive mixture before it enters the cylinders so as to render the same highly explosive and thus increase the efficiency of the motor.

Another object of my invention is the provision of a carburetor in which a plurality of substantially conical atomizer nozzles are used to engage more or less in openings of a movable plate and in this manner provide additional means for regulatlng the air supply to make the mixture more or less rich accordin to requirement.

Still another object of my invention is the provision of means coupling the regulating levers controlling the fuel and the air supply to allow an adjustment of fuel and air supply within any desired or required proportions.

further object of my invention is the provision of a carburetor of comparatively simple and inexpensive construction, yet durable and highly efficient in its operation.

A still further object of my invention is the provision of an attachment to the carburetor to be used with heavy fuel as for instance crude-oil allowing the starting of the engine by benzine or the like pure fuel.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be more specifically defined in the appended claims.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a sectional top plan view of the carburetor constructed according to my invention, seen on line 1-1 of Fi re 2.

Fig. 2 is a vertical section through the carburetor on line 2-2 of Figure 1.

Fig. 3 is a top plan view of the carburetor.

Fig. 4 is a sectional top plan view seen along line 44 of Figure 2.

Fig. 5 is an outer front view of the carburetor.

Fig. 6 is a sideelevation thereof.

Fig. 7 is. a sectionalelevation of a carburetor, attachment using crude oil, the section being taken on line 7-7 of Figure 8.

Fig. 8 is a front elevation thereof.

Fig. 9 is a side elevation of the attachment. a I I As illustrated in Figures 1 to 6 the casing of-the carburetor comprises an upper part 10, and a lower part 10 and has a head 11, auxiliary air inlet nipple 12, and fuel inlet nipple 13, and feed conduits 14 for the air when the engine runs idle and forpremixing; and 15 for the fuel which are connected with air inlet and fuel inlet respectively and arranged in a block or disc 16.

A screw plug, 17 constitutes a closure'and a similar plug 18 regulates the air inlet for the auxiliary air.

A valve seat 19 is arranged in the casing 16 to seat a needle valve 20 controlled by a spring 21 within a housing 22 slidably arranged in a socket 23. w

The valve is controlled by the head of a lever 24 on a pin 25 towhich it is secured at one end and which outside of the casing has attached thereto a regulating arm 26.

The position of this arm and therefore also the regulation of the suction stroke can be adjusted by means of a regulator bar or rod 27 about which a spring 28 is wound between a pin 29 or arm 26 and a pin 29 adjustable in aslot 30 of a regulated arm 31,

and the outer ends of rod 27 carry regulating nut- 32, 33, respectively.

For the regulation of the air amovable plate 34; is transversely arranged within the casing which has openings 35, 36, through which the upper ends-of the substantially conical nozzles 37, 38, extend, which are preferably pairwise arranged. The plate has a central sleeve 39 formed therewith surrounding the socket 23 and vertically slidable along the outer face thereof.

On one side the Sleeve has a member-40 formed therewith provided with a recess 11 in which engages the head of a lever 42,the opposite end is secured to a pin 43 on arm 31. A suitable filter plate or screen 45 is arranged to produce a scavenging of the air,

The operation of my device will be entirely clear from the above description and by reference to the drawings, and 1t Wlll be evident that I have invented a carburetor allowin a re ulation'of the richness of the explosive mixture by the proper adjustment of plate 34: relatively to the conical nozzles 37, 38, to enlarge or decrease the width of the openings 36 admitting the air, and by the proper adjustment of the fuel control. Moreover, the great number of sprayer nozzles will permit an intimate mixture .of air and fuel to obtain the best possible results and to produce a smooth running of the engine. The suction stroke is regulated by the proper adjustment of regulator barQT by means of the regulating nuts 32, j

It will be clear that with the use of a heavy fuel, casing 46 is attached by means of the screw 49 to nipple 12 andthe'regulation of the air admission is efiected by the proper adjustment of the screw in nipple 50 while the fuel inlet is regulated by the proper manipulation of screw 51. Y

I have, furthermore, provided an attachment to the air conduit of the carburetor in case crude-oil is to be used or other heavy fuel and it is necessary to start the engine with gasoline or benzine.

It will be understood that I have described and shown the preferred form of my device only, as one example of the many possible ways to practically construct the same, and that I may make such changes in the gen eral arrangement-thereof and in the'con struction of its minor details as come within the scope of the appended claims without departure from my invention and the principles involved. 1

Having thusdescribed my invention, what I. claim as new and desire'to secure by Letters Patent is: r i

1. A carburetor comprising a casing, a plurality of atomizer nozzles in said casing, a movable plate transverselyarranged in said casing, and having a plurality of open ings through which said nozzles extend more or less to regulate the air supply, a fuel valve, a casing therefor, means engaging the top of said casing to regulate the supply of fuel through said valve, and connect-ions between aid fuel regulating means, and said air regulating means for adjusting the feed of air and fuel in desired proportions.

2. A carburetor comprising a casing, a socket therein having an upstanding hollow stem a spring controlled fuel Valve, slidably arranged in said stem, an outer sleeve vertically reciprocating along the outer face of said stem, said sleeve having a recess on one of itssides, a partition having a plurality' of openings formed with said sleeve, a plurality of atomizer nozzles extending through the openings in said partition, and aregulating lever having a head engaged in the recess of said sleeve, a regulating lever for the fuel valve, a connection between both levers, and m'eansto adjustsaid connection to adjust both fuelv andlair controls to produce the proper mixture of air and fuel,

3. In carburetoiya casing, a transverse partition movably arranged within said casing andfhaving a plurality of openings, a plurait; of substantially conical atomizer nozzleswithin said casing extending with its upper partsathrough saidopenings, a means for vertically reciprocating said plate to regulatethe widthof said openings by closing the sa! e moreor less by the conical nozzles to regulate the supply of air, conirolmeans for-the-lair supply, control means :forthe fuel supply, a; connection between both control means and means to adjust said connection to produce a mixture of air and fuel in the proportions required.
